The state-of-the-art extrusion product line ECO CONCEPT meets all possible requirements of modern extrusion. The new EC extrusion lines convince with the highest functionality, perfect technology, ergonomic handling and design. Developed on the basis of customer process  analysis and state-of-the-art extrusion and energy technology, the extrusion product line ECO CONCEPT convinces through it revolutionary concept of energy saving profile extrusion. 
ECO Plus Concept is the new dimension on the extrusion scene, to offer an optimal solution for energy and environment in the extrusion. ECO Plus Concept is a patented technology for energy saving system, which was developed by our headquarter in Austria on the basis of reliable know-how and experiences in the extrusion business since many years. There're two alternative for ECO Plus Concept: Central Vacuum Energy Saving System, Control Vac System.

ECO Tech 
Energy saving systems
All of SPG's energy-saving systems are a part of SPG's extrusion systems. The biggest energy saving is achieved in the extruder drive and the vacuum pumps in the calibration table. The fully automated energy systems control and optimize the consumption of energy in the dry calibrators, water vacuum tank and water/air separation. By using the energy system, it is possible under optimum conditions to save up to 85% of the line's entire consumption in the area of the calibration table.
Design 
Standard design
Vacuum supply in the dry area with conventional vacuum pumps, in the wet area with separation tank including side channel blower and water pump

ECO Plus Haul-off & Cutter Combination
Equipment consisting of a massive, painted base frame designed for uptake of the caterpillar-cutter unit. Haul-off and cutter can be disassembled easily and be placed next to each other in a distance of max. 1meter. Easy access on operating side due to sliding doors. The machine is controlled by B&R control system.
The driving system of haul-off unit - 2 pcs three-phase AC-motors, directly connected with the reduction gear and driven by 1 pc frequency converter - transfers the adjusted haul-off force. By means of freewheel or optionally by servo drive.
The cutting unit is affected from the bottom up and is moving according to three-dimensional movement to ensure the cutting of profile without deformation. Heating method of knife is conduction heating, to ensure precise temperature. Fastening of knife is with four points' location, pneumatic uniformity and automatic tensioning to extend the life time of knife. Stable guides on the side are adjustable to the profile width and pneumatic profile clamps. The cutting impulse from the cutting program. The cutting length can be measured through encoder impulse and adjustable. The cutting in-feed is synchronous to the haul off speed via pneumatic cylinder or optionally by servo drive. Closed covering of the base frame for sound absorption.
The feature of haul-off & cutter combination

• Haul-off and cut-off installed in the same frame, push-pull style structure, safe and beautiful
• Al-Mg alloy for haul-off support, structure optimization.

·   Lifting device uses linear guide rail, stable and precise running.
·   High precision CNC system ensures caterpillar speed and torque synchronous.

• The maximum haul-off power: 30 kN, contact length:2300mm, haul-off pads:208pcs.
• The maximum haul-off speed: 10 m/min
• Advantages of Guillotine cutter without chips collection device: chipless, silence, economy
• High-precision, fixed length cutting, external covered, high power dust connector

PROFILE-TILTING TABLE
Suitable for profile lengths up to approx. 6000 mm and width up to 300 mm.
Consisting of a base frame and stainless steel table. Equipment adjustable to each extrusion center height by setscrews. Automatic tilting of cut profile according to alignment at the saw.
